👉 Radiac is a concept in physics that describes the movement of electromagnetic waves. It can be defined as the total displacement or spread of electric and magnetic fields over a region or surface. In the context of electronics, it refers to the motion of electrons or ions through a material's surfaces or between atoms. This motion can be described using the principle of wave-particle duality, where particles are described as waves with certain properties (like wavelength, frequency, amplitude) and therefore can move at different speeds
